Clutch disc assembly

Abstract

In a clutch disc assembly in which facings comprising cerametallic pads stuck to one faces of back plates are secured to both faces of a plate at an outer peripheral part of the clutch disc, a heat insulating material having a thickness which increases from the radial inside to the radial outside is held between the above-mentioned plate at the outer peripheral part and at least one back plate of a facing so that failure in engagement and disengagement of clutch can be avoided by preventing a strain caused by heat to be produced on the part of plate on which the facings are provided.

What is claimed is: 
     
       1. A clutch disc assembly in which facings comprising cerametallic pads secured to back plates are secured to opposite faces of a plate at an outer peripheral part of a clutch disc, characterized by that a heat insulating material is held between said plate and a back plate on said opposite faces, said insulating material having a thickness gradually increasing from a radial inside to a radial outside of said clutch disc.
